NOTES FOR POWER CYCLE TIMING CHARACTERISTICS
1.
Start-up time for crystals varies with load capacitance and manufacturer. Time shown is for an
11.0592 MHz crystal manufactured by Fox.
2.
Reset delay is a synchronous counter of crystal oscillations after crystal start-up. At 33 MHz, this time
is 1.99 ms.

NOTES FOR EPROM PROGRAMMING AND VERIFICATION
1.
All voltage referenced to ground.
2.
The microcontroller holds itself in reset for this duration when power is applied. No signals should be
manipulated during this interval since the microcontroller is ignoring inputs. At a 4 MHz oscillator
frequency, this period is 16.4 ms.
